SN74CBTLV3251DGVR

Overview

The SN74CBTLV3251DGVR is a low-voltage 1-of-8 FET multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. The device features eight data channels with a maximum on-resistance of 7 Ohms, a bandwidth of 200 MHz, and propagation delays of 6.4 ns (typical) and 6.8 ns (maximum). It is housed in a TVSOP-16 package.

Feature Summary

• Supports low-voltage operation between 2.3 V and 3.6 V for compatibility with modern logic families.
• Provides high-speed signal routing with a 200 MHz bandwidth and low propagation delay.
• Features low on-resistance to minimize signal attenuation across the selected channel.

Applications

• Portable equipment requiring low-power signal switching
• Battery-powered systems utilizing low-voltage logic
• High-speed data routing in communication modules

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-16 package and tape-and-reel packaging configuration. Confirm that the 2.3 V to 3.6 V supply voltage range aligns with the target system's power rails. Ensure the -40°C to +85°C industrial temperature rating meets environmental requirements. Cross-reference the manufacturer part number against official datasheets to validate pinout and electrical specifications before integration.

Selection Notes

Select this component when a single-channel 8-to-1 multiplexing function is required at low voltages. The TVSOP-16 package offers a compact footprint suitable for space-constrained designs. Consider the 200 MHz bandwidth and low on-resistance for applications demanding minimal signal distortion. Verify that the input logic levels are compatible with the 2.3 V to 3.6 V supply range.

Part Context

This device belongs to the SN74CBTLV3251 family of low-voltage analog switches. It serves as a cost-effective solution for signal routing in portable electronics where power efficiency is critical. The FET-based architecture ensures low leakage current and high isolation between unselected channels.

Replacement Considerations

SN74CBTLV3251D is a tube-packaged alternative from the same manufacturer with identical electrical characteristics but different packaging.
